Abstract
The purpose of this study is to investigate fluoride release in the oral cavity from polymer adhesive tape which is NaF coated PVA. 45 healthy adults were divided into 3 groups by the type of topical fluoride applied: 60seconds taste® APF gel (group 1), FluoroDose® varnish (group 2) and NaF-PVA (group 3). Topical fluoride was applied to the facial surface of maxillary 12 teeth and unstimulated whole saliva was collected to measure fluoride release after 1, 3, 6, 12, 24, and 48 hours. Fluoride-sensitive electrode was used for measuring the fluoride concentration in the saliva samples. All three groups showed significantly higher value for fluoride concentration than the baseline after 1 and 3 hours (p < 0.05). After 6 hours, group 3 showed significantly higher fluoride concentration than the baseline (p < 0.05) and also showed significantly higher value for fluoride concentration than group 1 and group 2. Between group 1 and group 2, however, there was no significant difference statistically with respect to fluoride concentration value (p > 0.05).
Key Words: Fluoride tape, Fluoride-ion concentration, Polyvinyl alcohol (PVA)
